"CV" = "control voltage" The 1/4" TRS connector on the pedal's cable plugs into a jack which supplies a DC source voltage. This voltage is scaled by the potentiometer inside the pedal and is returned to the jack. Moving the pedal rotates the potentiometer and varies the resistance, and this in turn varies the voltage. The changes in this voltage value control the value of the assigned parameter, so we say that it is voltage controlled. CV pedals are also known as Expression pedals. In general, they are NOT the same thing as volume pedals because they typically have linear pots rather than logarithmic pots. -- ______________________________________________________________ Richard Zvonar, PhD (818) 788-2202 http://www.zvonar.com http://RZCybernetics.com http://www.cybmotion.com/aliaszone http://www.live365.com/cgi-bin/directory.cgi?autostart=rz
